Does google offer expert servioce for optimization google ads etc
Unfortunately not. Google Shopping, Google Ads and Google Merchant Center is a 100% self serve business model. Meaning they give you the tools, you need to do all the work.
I have been managing Google Ads and Merchant Center for well over 15+ years, and it’s a lot of work. Just when you think you are finished optimizing, then Google comes up with another set of new features.
So a lot of work, feel free to reach out if you need any assistance.
